Some of the scenes appear to reference parts of the film One Flew Over The Cuckoo's Nest.

Charity Time to Change, which campaigns to change public attitudes towards people with mental health issues, says the band is in danger of making matters worse.

Director Sue Baker said: "The use of the word 'psycho' in a song and accompanying music video featuring people pretending to be psychiatric inpatients is unhelpful, damaging and disappointing when society is moving on from this sad and tired stereotype.

"We are sure the insult and harm was unintentional, or misjudged irony, but we are raising it as we know it will only serve to fuel stigma."

Ms Baker said the band appeared out of step "as so many musicians have recently talked openly about their experiences of mental health problems".

One of those musicians is Meighan himself.

He admitted to Q Magazine this month that he had suffered a secret breakdown, "making himself ill" last year following the death of a friend and his split from his partner.
